You plug in an ethernet cable, but nothing works. You check the rj45 colour code on both ends and spot something odd. The colors don’t match the standard. Ethernet problems like this can confuse anyone. Always look at the rj45 colour code before connecting a network cable. Use a cable tester to check your ethernet wiring. Remember, wire pairs matter more than matching colors. Grab a reference chart if you need help with ethernet cables.Spotting Non-Standard RJ45 Colour CodeImage Source: pexelsVisual CluesWhen you look at an ethernet cable, you might expect to see the usual t568a color code or t568b color code. Sometimes, though, the rj45 colour code looks different. You may notice stripes, faded colors, or even shades that do not match any standard. If you see wires that look odd, stop and check both ends of the cable.Tip: Always untwist the pairs and lay them flat. This makes it easier to compare the colors to a t568a color code or t568b color code chart.Here are some common signs that you are dealing with a non-standard rj45 color code:The wire colors do not match the t568a color code or t568b color code.Some wires have extra stripes or unusual shades.The order of the colors seems random or mixed up.The cable uses colors not found in standard ethernet cables.You might also run into problems if the cable is old or dirty. Dust and debris inside the connector can make it hard to see the true colors. Physical damage, like bending or crushing, can also change how the wires look.Pairing and ShadesYou may feel tempted to match colors from end to end, but the real key is correct pairing. Technical experts agree that keeping the right pairs together is what keeps your ethernet working well. If you mix up the pairs, your network cable may not work at all, even if the colors look right.A quick table can help you compare standard pairings:Pin Numbert568a color codet568b color code1Green/WhiteOrange/White2GreenOrange3Orange/WhiteGreen/White4BlueBlue5Blue/WhiteBlue/White6OrangeGreen7Brown/WhiteBrown/White8BrownBrownIf you see a cable that does not follow these patterns, check the pairs by untwisting and matching them up. Sometimes, you will find that the cable uses the right pairs but with different colors. That is okay, as long as the pairs match at both ends.You may also run into trouble if the cable is not the right type for your needs. Using a Cat5 cable instead of Cat6 can slow down your ethernet or cause problems with high-speed connections. Improper crimping or damaged connectors can also lead to network failures or complete disconnection.Remember: Always focus on correct pairing, not just matching colors. This will help you avoid headaches and keep your ethernet running smoothly.RJ45 Color Code Identification StepsImage Source: pexelsTools NeededBefore you start working with any ethernet cable, you need the right tools. Having the right equipment makes the job easier and helps you avoid mistakes. Here’s what you should have on hand:Cable tester: This device checks if your ethernet cable works and if all wires connect correctly. Some cable testers can even show you which wire is broken or out of order.Multimeter: You can use this tool to check for continuity and make sure there are no shorts in the cable.Reference charts: Keep a chart for the t568b color code and other wiring standards nearby. This helps you compare what you see with what’s correct.Wire stripper: This tool lets you remove the outer jacket of the cable without damaging the wires inside.Crimping tool: You need this to attach a new rj45 connector if you have to re-terminate the cable.Flashlight: Sometimes, you need extra light to see the wire colors clearly.Tip: Good lighting and a clean workspace help you spot color differences and avoid mixing up wires.Many cable testers offer advanced features. Some can measure cable length, check for signal loss, and even test for Power over Ethernet (PoE). Others use LEDs to show if each wire connects properly. Testing devices like the Fluke LinkIQ can diagnose problems like crosstalk or signal loss. These features help you find and fix issues fast.Mapping WiresNow, let’s get into the process of mapping the wires. This step is where you match each wire to its correct pin in the rj45 connector. You want to make sure the cable works for ethernet, even if the rj45 color code looks different from what you expect.Strip about one inch of the cable’s outer jacket. Be careful not to nick the wires inside.Untwist the wire pairs and straighten them out. Lay them flat so you can see all the colors.Compare the wire colors to your reference chart. Even if the colors are odd, focus on keeping the pairs together.Arrange the wires in the order you want for the rj45 connector. Use either the T568A or T568B standard, but stay consistent at both ends.Trim the wires so they are even. This helps them fit into the connector.Insert the wires into the rj45 connector. Double-check the order before you crimp.Use your crimping tool to secure the connector.Test the cable with your cable tester. Make sure each pin connects to the right spot at the other end.Note: Always check both ends of the cable. The pinout must match for ethernet to work. If you see a non-standard rj45 color code, write down the order for future reference.Industry standards like T568A and T568B, set by the Telecommunications Industry Association (TIA) and Electronic Industries Alliance (EIA), define how you should map wire colors to pin numbers. These standards help everyone create cables that work with all devices. The IEEE 802.3 Ethernet standard also explains which pins send and receive data. Following these steps and standards keeps your network stable and fast.Custom DiagramWhen you run into a non-standard rj45 color code, drawing your own diagram can save you time later. A custom diagram shows exactly how the wires connect inside the rj45 connector. This is helpful if you need to fix the cable again or explain the wiring to someone else.Here’s a simple way to make your own diagram:Pin NumberWire Color at End AWire Color at End B12345678Fill in the table with the actual colors you see at each end of the ethernet cable. If the colors do not match the t568b color code or any standard, this table helps you keep track. You can also take a photo of the cable ends for your records.Pro Tip: Save your diagram or photo with the cable or in your network documentation. This makes troubleshooting much easier if you or someone else needs to check the cable later.Technical guides recommend documenting your custom wiring, especially for non-standard setups. This helps you avoid confusion and keeps your network running smoothly. Consistency and clear records are key when working with any rj45 connector.RJ45 Connector TroubleshootingContinuity TestingWhen your ethernet cable stops working, you need to check if the wires inside connect the right way. That’s where a cable tester comes in handy. You plug both ends of the cable into the tester. The device checks if each wire goes from one end to the other without any breaks or shorts. This is called a continuity test.A continuity test is the first step in finding problems with an rj45 connector. If the tester shows a problem, you know there is a break or a short inside the cable. Sometimes, the tester will show that all wires connect, but your ethernet still does not work. This can happen if the pairs are mixed up or twisted the wrong way. In that case, you may need more advanced testing devices or a loopback test. A loopback test sends a signal through the cable and checks if it comes back. This helps you find deeper problems like signal loss or poor connections.Tip: Always start with a continuity test. If you still have trouble, try a loopback test or check the cable with a different device.Some advanced testers also measure resistance and signal quality. They can tell you if the cable can carry data at high speeds. These extra tests help you find problems that a simple continuity test might miss.Common IssuesYou might run into several problems when working with an rj45 connector. Here are some of the most common issues:Mismatched pairs: The wires are not paired correctly. This can cause slow speeds or no connection at all.Split pairs: The wires from different pairs get mixed up. Your ethernet might pass a basic test but still fail to work right.Shorts and opens: A short means two wires touch when they should not. An open means a wire does not connect at all.Intermittent connections: Sometimes the cable works, and sometimes it does not. This can happen if the wires do not fit tightly in the connector.Physical damage: Bent pins, crushed cables, or worn-out connectors can all cause trouble.Technical reports show that even small differences in wire thickness can cause problems. For example, if the wires are too thin, they might not fit the rj45 connector well. This can lead to loose connections, especially at higher speeds or when using Power over Ethernet. Always check that your cable and connector match in size.Note: Using certified cables and connectors helps you avoid many of these problems. Always follow the wiring standards like T568A or T568B.If you keep running into the same problems, you might need to look at your installation process. Make sure you do not untwist the pairs too much. Only expose about one inch of wire when you strip the cable. This keeps the signal strong and reduces errors.Fixing and Re-TerminationIf you find a problem with your rj45 connector, you can often fix it by re-terminating the cable. Here’s how you can do it:Cut off the old connector with a clean snip.Strip about one inch of the cable jacket. Be careful not to damage the wires inside.Untwist the pairs just enough to fit them into the connector. Keep the twists as close as possible to the connector.Arrange the wires in the correct order for T568A or T568B.Trim the wires so they are even.Insert the wires into a new rj45 connector.Use a crimping tool to secure the connector.Test the cable again with your cable tester.Some new systems, like the REVConnect, make this process even easier. They use a special tool and a universal cable manager. You do not need to untwist the pairs as much, which keeps the signal strong. Even if you do not have special tools, you can still get good results by following the steps above.Pro Tip: Always test the cable after you fix it. If you still have trouble, check your work or try a new connector.Best practices say you should always follow industry standards when you repair or re-terminate a cable. Use the right tools, keep your workspace clean, and document your work. This helps you and others fix problems faster in the future.If you see the same issue again and again, check your cables and connectors. Make sure they are certified and match in size. Sometimes, the problem is not with your work but with the parts you use.Network Cable DocumentationLabeling WiresYou can save yourself a lot of trouble by labeling every network cable as soon as you make it. Clear labels on both ends help you know exactly where each cable goes. Use durable labels that won’t fade or fall off. Write down the port number, device name, or even the room location. Some people use color-coded wraps or cables to make things even easier. This helps you spot different network segments at a glance.Pro Tip: Good cable management can cut troubleshooting time by more than half and help your equipment last longer.Many companies use cable management tools like D-Rings, patch panels, or vertical organizers. These tools keep your cables neat and easy to trace. When you label and organize your network cable setup, you avoid confusion and reduce the risk of unplugging the wrong wire. You also make it easier for anyone else who works on your network later.Here’s a quick checklist for labeling:Label both ends of every cable.Include port numbers, device IDs, or destinations.Use color codes for different network segments.Update labels if you move or change cables.Sharing InfoYou should always keep records of your network cable layout. Draw diagrams or use spreadsheets to track where each cable runs and what it connects to. If you make changes, update your records right away. Write down the date, what you changed, and who did the work. This way, you build a history that helps with future upgrades or repairs.When you work with other technicians, share your documentation.

A team from Max Planck Institute for Informatics, Saarland University, Carnegie Mellon, CNRS LTCI, Telecom-ParisTech and Aalto University have authored a paper describing their work in "iSkin: Flexible, Stretchable and Visually Customizable On-Body Touch Sensors for Mobile Computing." They envision a digital life where one can use a comfortable, light wearable such as finger strap, arm sticker and even keyboard extensions on rollout paper attached to the wrist device for mobile touch input. A video shows iSkin in action. In one scene, it is an arm sticker to control a music player; the person presses various places on the sticker to play a song or adjust the volume. Another scene shows somebody using a finger overlay to accept an incoming call. The video also shows a keyboard extension that can be rolled out on demand for a smartwatch text entry. iSkin is flexible and stretchable; it can detect touch input with two levels of pressure, even when stretched by 30 percent or when bent with a radius of 0.5 cm, they said. It can be of different shapes and sizes for different parts of the body—-such as fingers, forearm, or ear. A key feature is its construction of biocompatible materials. That requirement was not taken lightly. The authors in the paper said "iSkin should be non-toxic, and easily cleanable, washable, or replaceable in order to limit the accumulation of pathogens such as bacteria. Moreover, the properties of skin vary greatly." As "wrinkliness, oiliness, and distribution of receptors, sweat glands, and hair follicles" vary across body locations and individuals, they said this presented a requirement for materials and adhesives compatible with natural skin and exhibiting a high variability of form factors. What they came up with is "based on advances in electronic skin (e-skin) and soft-matter electronics, an active research field in robotics and material science." The sensor can be thought of as a sandwich composed of multiple layers. They wrote that "iSkin is made of multiple layers of thin, flexible and stretchable silicone. The base material is polydimethylsiloxane (PDMS), an easy-to-process silicone-based organic polymer. PDMS is fully transparent, elastic, and a highly biocompatible material." A Reuters report by Matthew Stock on Monday had further comments on the materials and the research from co-developer Martin Weigel, who said the technology was initially coming from robotics :where it's used to give robots kind of a feeling similar to the human body, to human skin. However, we are the first to look into how we can use it on the body to control mobile devices; so as a kind of second-skin which nicely conforms to your body." Weigel said carbon particles inside the silicone make it conductive so they can use it for electronics. The Reuters report added that the stickers are attached to the body using a medical-grade adhesive, easily peeled off after use without hurting the skin. In their paper, they said that study results showed the sensor remained functional under typical and extreme deformations occurring on the human body; also it accurately sensed touch input when worn on various body locations. Right now there are no signs that you will find iSkin sensors in the marketplace; this is a proof of concept, said the authors, of on-skin touch sensing "that bears some promise over rigid sensors and computer vision based solutions."

Overview: This article presents a review of control and modulation methods for DC-DC power converters. The focus is on high-performance power converters, but the methods are applicable to any DC-DC power converter. Pulse-width modulation (PWM) and small-signal-based feedback controls forms the basis of many commercial controller executions for DC-DC converters. Alternatively, many large-signal approaches are available. This article aims to provide a review of control and modulation methods, as well as methods for controller tuning, for DC-DC switching power converters.Do conventional control methods maximize efficiency?New, higher-level controls are inspired by the development of fast wide-bandgap switches in addition to the ongoing progress in digital signal processing and sensors. Fast processors and digital signal processing make new computational techniques for power converter control possible. Traditional methods of control almost never maximize available performance. The focus here is on high-performance converters, a rapidly expanding industry.Role of Converter TopologyThe converter topology serves as a constraint in the control process. In theory, with the right constraints, a single control method can be applied to a wide variety of circuits. Power regulation for digital electronics is very often done by voltage regulation. Using LED lighting encourages the use of current-regulated loads. Most battery chargers have settings for regulating both the voltage and the current. DC sources and loads in microgrids, as well as digital loads, benefit from droop relationships. The methods presented are not limited to these converter types; rather, they can be used with any DC-DC converter. Hard-switched converters, state feedback control, and large-signal tuning are all highlighted.Control Objectives for DC-DC ConvertersTable 1 summarizes the four different types of goals that DC-DC converter controls should meet. Both static and dynamic conditions are part of the operational necessities. Control is not always related to other operational needs, such as electromagnetic interference (EMI), efficiency, and dependability. The need for fault management and protection are typically dealt with independently. Some large-signal controllers can directly manage many requirements in Table 1 that appear to be independent. The entire set of specifications shown in Table 1 is related to converter design.Table 1. Converter Objectives With Control Implications. Source: IEEE Open Journal of Power Electronics Inductor and capacitor selection affect the ripple bands and slew rate limits. Layout and parasitics both have an impact on EMI. However, it is theoretically possible to define a cost function J(x) that is connected to all of the operating variables and converter parameters, as shown in equation (1)  where ai are weights, x are independent variables, and fi(x) are functions of x and other parameters. The root-mean-square (RMS) current and flux (associated with losses), the output voltage error and ripple, the rise time of the load current, the peak voltage stresses of the device, the peak junction temperature, and the switching frequency variation are examples. To take into account various operating points, converter topologies, and component considerations, the multi-objective optimization of power converters is formulated as a geometric program, a type of convex optimization problem. To increase the power density of DC-DC converters, it is also possible to incorporate electromagnetic effects and thermal management into the electrical design. Similar terms could have been used to define a performance index, which is the opposite of a cost function. An optimization problem can be formed from a design or control problem, and the cost function must be minimized.Control Methods to Address Timing ProblemThe timing issue is simple to frame but difficult to solve in practice. With simplified requirements, it is easy to solve for simple converters. However, the difficulty of the issue increases with the inclusion of further specification details and uncertainty. It does inspire particular methods. The goal of trajectory-based controls is to reformulate the timing problem as one with state variables. Alternatively, fast response relied on dedicated circuits like clamps. A converter is even modified with additional switches and devices to achieve faster disturbance rejection.Challenges with Solving the Timing ProblemBecause there is no simple solution to the generic switch timing problem, designers are limited to feasible methods. This typically adds two additional restrictions to those listed in Table 1. There are limitations on the converter's operating regime. Setting a mandatory minimum switching frequency is a typical example. The foundation for control design and operation is a simplified model of the converter. Implementing a small-signal linearization of an averaged model is a classic example. The first restriction reduces the amount of timing flexibility and makes the issue a cycle-by-cycle duty ratio. The second results in model-limited control, which may prevent access to the converter's full dynamic capabilities.Factors Affecting the Control MethodsThe block diagram of a fundamental feedback and feedforward buck converter control system is shown in Fig. 1. To prevent ripple effects, the feedback sensing block is band limited. Additional signal conditioning and analog-to-digital converters (ADCs) are required for digital control. For accurate output regulation or tracking, output feedback is necessary. Control or current-regulated loads can both benefit from inductor current feedback. Either output feedback or state feedback can be used to control a converter. Using input voltage, load current, or other data, feedforward action can improve disturbance rejection, lower audio susceptibility, and lower output impedance. To produce the gate signal for the controllable switch, the controller drives a modulator. A limiter function is necessary for the modulator in a boost converter. Fig. 1. Feedback control of a buck converter. Source: IEEE Open Journal of Power ElectronicsSmall-Signal ControlThere are a wide variety of uses for small-signal controllers. Network analyzers and other testing tools support the useful connection to conventional frequency-domain design procedures. Small-signal controllers have distinct soft start and inrush management, protection management, and strategies to adapt to a broad load range due to the need to design for a specified operating point. Improvements in dynamic performance are the subject of a large body of research. The advantage of connecting to well-established frequency-domain design tools is a benefit of small-signal models and tuning. However, small-signal methods and models do not offer a systematic way to run dynamic response up to slew rate limits and do not take into account nonlinear factors like duty ratio saturation or current limits. Also, small-signal controls require independent blocks for large-signal startup and fault protection.Large-Signal ControlLarge-signal controllers, on the other hand, can facilitate changes between seemingly incompatible operating states. Conversions can make use of the slew rate capabilities of the converter. Both switching boundaries and operating points can be applied to the problem of starting up and handling faults. Large-signal controllers provide useful alternatives for applications requiring fast dynamic response or a broad range of load conditions. Geometric controls can be visualized as involving multi-segment boundaries for functions like startup and fault protection. To conclude, the robustness and sensitivity issues between small-signal and large-signal methods are actually fairly consistent. Knowing the parameters is helpful for both; feedforward is advantageous for both; the model performs best when it is accurate and complete; and adaptation to changing circumstances is helpful for both.Summarizing the Key PointsNew, higher-level controls for power converters are possible due to the development of fast wide bandgap switches, digital signal processing, and sensors. Converter topology serves as a constraint in the control process, but with the right constraints, a single control method can be applied to a wide variety of circuits. Pulse-width modulation and small-signal based feedback controls are commonly used for converters, but large-signal approaches are also available. Geometric controls based on piecewise-linear large-signal analysis can provide the quickest dynamic response for high-performance DC-DC converters. Low-cost digital controls make it possible to sample quickly and switch boundary controls, and high-performance DC-DC converters may benefit from the use of online adaptive geometric controls.ReferenceKapat, Santanu, and Philip T.

Developer of force-sensing technology, Peratech, is aiming to give users of smartphones and tablets a more intuitive user experience while unleashing more creative opportunities for product and app developers by adding new ways for consumers to interact with their devices. The most recent forecasts indicate that shipments of smartphones will exceed 1.5bn units in 2016 with tablet shipments expected to reach at least 240m. Peratech is working with several well-known manufacturers of these devices to add QTC force sensors to multiple surfaces on their products. The sensors, which are supplied in the form of a polymer membrane as thin as 50µm, can be applied under displays, along the edges and on the backs of handheld consumer electronic devices. They can be configured to sense X-Y position through touch and applied force in the Z-axis. There are single-touch and multi-touch versions.Sensors used under a display can sense the force applied across the entire screen and compute the touch pressure for individual zones or functions. Alternatively, they can provide discrete pressure buttons in regions that match the graphical user interface layout. Home buttons can be made multi-functional and wear-prone dome switches replaced with a force-sensing button where a light touch of the finger gives a quick wake up to check the time or messages and a firmer press reads the fingerprint and unlocks the phone.QTC sensors work under most surfaces. When applied to the sides and/or back of a smartphone, they sense the user’s grip and the amount of pressure applied, which can be used to control basic functions or apps. In addition, the back of a smartphone or tablet can be configured as a single- or multi-zone touch pad, opening up many more options for gaming input and interaction. On the device edges, QTC sensors may be used as switches and volume or brightness controls. Here, cutting holes in the case is eliminated and it’s easier to make products more robust and waterproof.Peratech CEO, Jon Stark, commented: “Adding a third dimension – force – to the user interface of a smartphone or tablet, and being able to do that anywhere on the surface of the device, offers designers infinitely greater opportunity to differentiate their products. They can become more creative with the interactions they provide, as can app developers, while at the same time making devices more intuitive and responsive”.Reference:FSG15N1AFS20-5-0-0000-1500FC2231-0000-0010-LFC2231-0000-0025-L
